The new Final Fantasy XIII trailer features Serah, the younger sister of heroine Lightning and girlfriend of bandana-wearing character Snow. According to some, Serah's character design isn't new.

Her hair style, clothes and even stockings look remarkably similar to Kurumi Imari, a character in high-school witch-coven sex-and-horror erotic game Bible Black. The title was released for PCs in 2000 and later adapted into a video anime. Final Fantasy XIII will be released on the PS3 in Japan this December.
